How effective is it? 98% effective when used correctly. 2 women in every 100 will get pregnant each year using this method.

How does it work? Condoms are made of thin latex or plastic and are put over the erect penis before sex. They stop sperm from entering the vagina.

Advantages: Available for free from sexual health clinics and can be bought in chemists and supermarkets. ONLY condoms can protect from STIs. No serious side effects.

Disadvantages: Putting it on can interrupt sex, will not work effectively if it is the wrong size, the man has to withdraw and remove the condom as soon as he has ejaculated and throw it away without spilling any semen.

Other facts: You must use a new condom every time you have sex. Needs to be put on before the penis touches the woman’s genital area, oil-based products can damage latex condoms. They are available in all sorts of shapes, sizes, colours and flavours!
